Acrab的音标

Conclusion: The multiple-antibiotic-resistant active efflux system gene acrAB of Salmonella typhi shows high homology in bases, amino acids and protein structure with that of Escherichia coli and it is the possible reason that Salmonella typhi is resistant to multi-antibiotics without similar chemical structure.

结论：伤寒沙门菌acrAB主动外排系统在结构、碱基序列和编码的氨基酸序列上均与大肠杆菌有很高的同源性，它可能是伤寒沙门菌引起多重耐药的主要原因。

The investigation suggests that Mar phenotype of Escherichia coli be determined by the levels of active efflux system acrAB gene expression, and the expression of acrAB gene should be regulated by mar operon.

本研究表明大肠杆菌acrAB表达水平决定了大肠杆菌多重耐药表型，mar可能调控acrAB的表达。

Objective: To identify the sequence of the multiple-antibiotic-resistant efflux acrAB gene in Salmonella typhi 275 ( a clinically isolated strain) and analyze its structure, amino acid sequence.

目的：伤寒沙门菌275主动外排系统acrAB全基因测序并分析其结构。
